So at lunchtime today it was off to the PC shop where I purchased a new 1G stick of ram. "You right to install it?" the tech asked. "No probs!" I replied, trying to sound more confident than I felt.
The first thing I did upon getting home this evening was take the case off the old pc and install the new ram. And it worked! Yay me! I actually accomplished something technical without assistance! Okay, so I didn't exactly design a space shuttle but I couldn't be happier if I had.
And now my pc is sweet, purring along as it did when it was brand new and shiny.
